With help from a company called JESS3, Foursquare will give each user an iVOTED badge after they checkin.

What's interesting about this is the Foursquare website that goes along with the promotion, which includes a real-time map indicating user activity (at the time I wrote this post, embedding the map wasn't functional).

This is a great example of how social media can help crowd-source hyper-local data for brands around any event — major or not. And despite not being a reliable source for voter turn-out overall, it will be interesting to see the cross section in the U.S. of active voters who are also location-based service users.
